Title: Silent chain transmission device
Inventor: WADA MASAICHI
IPC: F16G13/06
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the contact area of engagement parts opposed to a tapered part from reducing and suppress the increase of the bearing pressure by arranging guide ring plates oppositely to the outside face in the tooth width direction of a sprocket and bending them as separating from the outside face in the tooth width direction toward the tip in the sprocket side. SOLUTION: Guide ring plates 14 are connected to major ring plates 13 via a connecting pin 12 in the outside face 11b in the tooth width direction of a sprocket 11 and the guide ring plates 14 have a function of regulating the movement of a silent chain 10 in the tooth width direction relative to the sprocket 11. The tip part 14 of the guide ring plate 14 in the sprocket side is bent outward in the tooth width direction. Compared with a case where tapered parts 11c are notchedly formed in the sprocket, the contact area of the engagement parts can be increased so that the increase in the bearing pressure can be suppressed and the durability and abrasion resistance of the sprocket 11 can be improved.

IPC: G11C11/401
Filed: 1982-09-29
Abstract: PURPOSE:To delete noise out of a cell plate by providing a noise cancelling word line which is driven concurrently with a word line. CONSTITUTION:The inverted signal of a word line WL (m) is supplied to the noise cancelling word line NWL1. This line WL (m) has the voltage of an earth level in a non-selection mode and is at a high level when it is selected. Therefore the line NWL1 is set at a high level when a memory cell is set in a reading or writing state and then set at an earth level when a certain memory cell is selected. As a result, the capacitive coupled noise that is applied to a cell plate CP1 from the line WL (m) through a coupled capacity Cwp is cancelled. Thus the cell plate voltage is kept at a constant level.
